Specification of Letters Patent.

Patented Apr. 7, 1914.

ilpfnicato' inea February' is. 1'912. semi No. Gianni.

To all whom it may concern Be` if, known that I, THOMAS Jl. Linosiv, a citizen of the United States, residing at Indianapolis. in the county o'f Marion and State if-Indiana. have invented a new and useful Driving-Axle, of which the following is a specification.

The object oi my 'invei'ition is to produrre improvements in a driving axle structure for aiitoi'iioliiles of the general type Shown in iny pending application Serial No. 642,799. In that application I disclose a rear axle strugtiire huilt np of a niin'ilie-r of independent units wliieli can be readily and independ ently se' arated from and reasseinhled with the other units, and the present consti-nello? invii general ivay follows tlie disiflosnres o that application. x Y

The accompanying drawings illustrate niy invention.

Figure l is a fragmentary horizontal'seeimproved driving axle` strutture;

n'lnali receives a cireumerential series of tion of iny V Fig. a plan on a smaller saale: Fig. il a fragmentary detail in partial ver-tival seetioii of a support for the brake lieaiiis; li'ig. 4 a section on line 1--l of Fig. 3: and Fig. 5 a fra rnientary detail of the interlock lietiveen t le casing' tube and the liraliesiipport,

ln the drawings, A indu-aies a central easing iiiiit having a` i'oniovalfle rap covering an opening' through whit-li ilie dilii'irential Leni-ing nnit C may be readilyY withdrawn. The ventral easing unit A is flanked at earth side h v sha item1-wheel units B, B, and re inovalily mounted in the central easingi unit A is a driving pinion nnit D. While these several units A. F. C, and D are. in general, like the eorresponrvling units in the application already mentioned, they nach differ in sonie details of oonstrnitioii.

The iinit (l eoniprises a main @aging ineni Mer 13 having annular liearingsnpportinii ineniliei's 14 and l5 which are 'formed for rerelition in seats 16 and 17 i'esiiieetively. l'l'oi'inecl in` the easing' unit A and supple nienteil hy removable caps 16 and 1T.y resina-lively, the raging unit C tlins being reiiiovalily held inplace Within the easing unit A. ln my present construction, the poi-tion lfl rarrie's a plain hearingr hashing IS of de slialile :i'xial length Within ivllii'li in jour-- naleil llio c vlindi'iral sleeve 19 of the inain holly o'l" a diiieiential gearing 21 wliii'lL in the present drawings, has some details of construction ivliieli will form the siilijei't iiiattcr of a later application. Axially opf posite the cylindrical sleeve 19 is a sleeve 22 which is also a part of the main body of the diliereiitial gearing :2l and is formed to rereive an annular track for a series o roller hearings 2l which are also received within an annular track 25 supported in the bearing receiving portion 15 of the cage 13.

The roller hearing formed lby the trat-lis 23 and 25 and the series of rollers Qa-Iis, in the 65 ypresent instance, of that type in which axial thrust is resisted by confined ends of the rollers acting against radial flanges forming part of the roller tracks, and the tr ck 23 is held upon the main body of the d erential gearing against axial movement in one direction. The track 25 is fitted Within the portion Vl5 so asV to be readily axially movy able and is abiitted by an adjustable abutinent ring :2G ivliich is threaded into the por- 7S tion l5. The alontinentQG also' forms an aliotinent or iholder for the ball race 27 tliiist-iesisting ballsZS, the` other track 29 f sail balls lying against the outer end of `he sleeve By this arrangement, the bearing .Tf--QS-f-*QQ takes the thrust of the main gear Ell o the differential gearingand this relieves the bearing Z4-:E25 lfrom any material thrust. It will be noticed that in adjustment of the abutment y26'axial1y determines the axial position of the main 1 gear 31 and will thus determine the meshing oi that gear with the driving pinion 32 of the driving pinion unit D. y A The unit B consists in part of a tubular easing meniliei' 41 which I prefer (although not neressarilyl to form of commercial tubing iiliirli i'nav he suliieiently upset atione @nil to perrnii flaring, as indicated at 42, and to permit the formation of an outwardly extending: radial Hang-e 43 for recept-ion in a nonkel Vl-l formed in the end of the casing inrniliei- A. heini; firmly bolted to the easingl inonilier h v fasteningf bolts 45, the nuts 45' of wliii-li nia'v he readily withdrawn in order to permit the withdrawal of the unit B. The inter end of the tiilie 41 is also upset at a point near its outer end so as to form an oiitivaril (ii-viiin'forential flange 46 which niav he Coiivenirntfly axially milled or out at one or more points. as indicated `at 46', Figs. l :mil fi. for the reception of an axially eX`- teni'l'ingi' finger l-T varried by a brake support'- iag' holly 48 which is sleeved over the oiiter 110 end et' a tube. 41 and abnts against the outer face et flange 4G.
